Description

Quest 506 High-Efficiency Overhead Dehumidifier 277V
The Quest 506 High-Efficiency Overhead Dehumidifier 277V is powerful and efficient for demanding commercial and industrial spaces. Its capacity makes it one of the market’s most powerful and efficient commercial dehumidifiers. Protect valuable assets and eliminate damaging moisture in your greenhouses.
Versatile Uses and Installation
Thanks to its unique design, this American-engineered dehumidifier can be used in various industrial and commercial spaces and offers impressive MERV 13 filtration.
- Quest 506 High-Efficiency Overhead Dehumidifier operates in any temperature between 56 and 95 degrees F.
- A gravity drain hose is included to remove the excess moisture it collects. You can either drain it outside or into a reservoir.
- This overhead dehumidifier can be ducted when necessary; intake and exhaust duct kits may be purchased separately.
Note: A remote humidistat is required for use. Our customers often choose the Quest DEH3000R controller.
M-CORR Technology
The Quest 506 High-Efficiency Overhead 277V commercial dehumidifier uses Quest’s patented M-CORR technology, which increases device efficiency using multiple recovery coils to cool air and recycle energy. Quest devices with M-CORR technology use less energy than traditional dehumidifiers, pulling 30 percent more water from the air and expelling less heat.
Maintain Optimal Humidity Levels
The Quest 506 Overhead dehumidifier effectively removes moisture and controls humidity, eliminating costly quality errors, preventing rust and corrosion, and maintaining the correct humidity levels for indoor growing spaces.
Overhead installation also saves floor space and helps mitigate moist air trapped near the ceiling.
Efficient Operation
The Quest 506 Overhead Dehumidifier 277V removes an industry-leading 506 pints of moisture daily, making it one of the most efficient high-capacity designs available.
Quest’s patent-pending coil technology allows for higher efficiency in a smaller unit. The 506 High-Efficiency Overhead Dehumidifier pulls only 11 amps and has a maximum efficiency of 8.1 pints/kWh. This complies with California Title 24 updated regulations for energy efficiency for both overhead (portable) and ducted (whole-house) installation. No high-capacity dehumidifier can remove 500 pints of moisture in such a small frame.
Using fewer amps means the unit generates less heat—another bonus if you use this model in growing spaces.
Quest 506 High-Efficiency Overhead Dehumidifier 277V Additional Features
- Long Power Cord: A 10-foot power cord makes installation easy in almost any location.
- Superior MERV 13 Filtration: Air exiting the dehumidifier is filtered with a MERV 13 filter, which catches particles like smoke, smog, bacteria, microscopic allergens, and debris. Filter changes are suggested for 6-8 weeks if the dehumidifier is used in growing spaces.
- R454B Refrigerant: The Quest 506 now uses R454B Refrigerant, which is more energy efficient and has a 75 percent lower global warming potential than R-410A.
- 5-Year Compressor Warranty: It’s backed by a 5-year compressor and refrigerant system warranty and a 1-year parts and labor warranty.
- Auto Restart: After power outages, this high-capacity dehumidifier returns to its previous settings once power is restored.
- Integrated Handle: Integrated heavy-duty handles make transporting easier. The threaded rod handles can attach to a 3/8-inch rod (not included) if you use it as an overhead dehumidifier. Moving this 280-pound model will require at least two people.
- Low Voltage Control Option: Wire the remote dehumidistat using a low-voltage terminal block.
- Remote Humidistat Required: Quest 506 High-Efficiency Overhead Dehumidifier requires a remote humidistat for use. We recommend the Quest DEH3000R controller.
QUEST’S PATENTED TECHNOLOGY | M-CoRR™
Providing the most energy-efficient dehumidification
The secret behind Quest’s unparalleled energy-efficiency is their patented multi-coil design, M-CoRR (short for Multi-Coil Refrigeration Recovery). You won’t find this technology anywhere else.
Engineered for maximum performance, Quest’s M-CoRR is the most energy-efficient and the best return on your investment, paying for itself in energy savings over time. M-CoRR’s innovative design performs better over a wider range of dew points, even at colder temperatures, and maintains capacity regardless of airflow fluctuations.
How Does Quest’s M-CoRR Technology Work?
Traditional refrigerant dehumidifiers have a single refrigerant-filled evaporator coil that cools the air passing through it to extract the water from the air. Once air cools below the dew point, water condenses. Energy captured in the refrigerant during water removal returns to the air in the form of heat at the second coil, the condenser.
The magic of Quest’s M-CoRR Technology is its multiple coils. Quest designed the typical evaporator coil into three separate refrigerant-filled coils: the pre-evaporator, evaporator, and recovery coil.
The first coil, the pre-evaporator, cools the air. The second coil, the evaporator, cools it even further to pull out the water. The third coil recovers the energy from pre-cooling the air and recycles it back into the evaporator for reuse.
What Are The Benefits Of Using M-CoRR?
Highest Efficiency. Lowest Energy Usage
Higher efficiency = lower electricity usage per pint of water removed. M-CoRR technology pulls more water out of the air per kilowatt hour than any other dehumidification technology. Period.
Less Heat Output
Inefficiency = Heat. It takes energy to run the fan and compressor in your dehumidifier. During dehumidification, this energy converts to heat that warms your room. The more energy your dehumidifier consumes, the more heat it expels. Quest dehumidifiers featuring M-CoRR technology are the most efficient dehumidifiers in the world, which means they put less heat in your environment.
More Capacity, Smaller Footprint
Your space is valuable. Dehumidifiers powered by M-CoRR are more compact. This technology averages over 20% smaller than traditional LGR dehumidification technology of the same capacity.
Wide Operating Rage. Tighter Control
Thanks to its multiple coils, M-CoRR technology equips Quest to maintain performance better than traditional dehumidification equipment, even in cooler temperatures and dew points, with less frequent and faster defrost cycles. Less time spent in defrost neutralizes spikes in temperature and relative humidity, keeping the environment consistent and, in indoor cultivations, VPD dialed in.
